FLUID-NOZZLE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed June 23,1905. Serial No. 266,575.

To LLZZ whom it puny concern.-

Be it known that we, JOHN DovE ISAAOS, a resident of Oakland, and JAMEs BUOKNER SPEED, a resident of Berkeley, Alameda county, State of California, citizens of the United States, have invented certain new and useful Improvements in Fluid-Nozzles; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to the class of nozzels and is especially applicable in connection with the piping of a fluid according to the art or method disclosed in Letters Patent of the United States, No. 759,374, granted to us May 10, 1904, to which patent reference is hereby made. In this method the fluid to be piped, together with a fluid of greater specific gravity, is caused to advance through the pipe-line with a helical motion about the aXis of the fluid content sufficient to envelop the lighter with the heavier fluid, thereby reducing the friction on the pipe-walls.

Our present invention consists in a special nozzle which is adapted to supply the fluids to the helically-riflled pipe-line which induces and maintains the required motion of the fluid content in such a manner as to give to said fluids an initial helical motion, thereby assisting in the inauguration and attainment of the required motion.

Referring to the accompanying drawings,v

Figure 1 is a side elevation of the apparatus for carrying out the method, the pipe-line A being broken to show the discharge end of the nozzle. Fig. 2 is an enlarged cross-section on the line w :0, looking back toward the nozzle.

A is the pipe-line, having on its interior a helically-directed obstruction a of suitable form.

B is the pump by which the lighter fluidsuch, for example, as oil-is supplied to the pipeline, and C is the pump by which the heavier fluid, such as water, is supplied to said line. The pi e b from the pump B communicates with t e rear end of the nozzle pipe D, the discharge end (1 of which proj ects, as shown, into the pipeline. Within this discharge end d are seated the helicallydirected flanges d, which impart an initial helical motion to the oil passing through the nozzle.

The pipe 0 from the water-pump C communicates with the pipe-line around the nozzle end. Between said pipe-line and the eX- terior of the nozzle end are seated helicallydirect ed flanges E, which give the initial helical motion to the water as it advances in the pipe-line to join the oil.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A nozzle, the wall of which being fashioned to form upon both its interior and exterior surface helically-directed flanges, in combination with a surrounding pipe extending therebeyond and having upon the interior wall of its extended portion similarlyarranged flanges.

2. In an apparatus for piping a fluid according to the method stated, and in combination with a helically-riffled pipe-line, a nozzle therewithin provided with means for delivering the fluids to the riffl ed pipe-line withv an initial helical motion.

3. In an apparatus for piping a fluid according to the method stated, and in combination with a helically-riffled pipe-line, a nozzel provided with helically-directed flanges for delivering the fluids to the riflied pipeline with an initial helical motion.

4. In an apparatus for piping a fluid according to the method stated, and in combination with a helically-riflled pipe-line, a nozzle for delivering two fluids with an initial helical motion, to the pipe-line, consisting of a pipe fitted to the pipe-line and provided interiorly with helically-directed flanges for delivering one fluid, and exteriorly with helically-directed flanges for delivering the other fluid.

5. In an apparatusfor piping a fluid according to the method stated, the combination of a helically-riffled pipe-line, a noz zle for delivering two fluids with an initial helical motion to the pipe-line, consisting of a pipe fitted to the pipe-line and provided ini In Witness whereof We have hereunto set teriorly With helically-directed flanges, and our hands.
